Network_error: No Proxycheckgateway found

[dp2010]

Tried to set it up in ubuntu and in debian but always get the error Network_error: No Proxycheckgateway found

started with: sudo unblock-proxy.sh dns --redsocks -d

Have you set up a valid DNS in /etc/resolv.conf and can you also ping domains like github.com ?
You also have to check the correct gateway to web with ip route show

Not all ubuntu / debian installations have curl installed by default. You'll also get the above error if curl is not installed.
Install it using apt install curl and it should work.

Curl should probably be added to Minimal requirements section of the README.
